摘要
At present many open-pit mines face serious threat of underground goaf in China. Take exploration and governance of goaf of a certain open pit mine of Pingshuo mining area as engineering instance, the risk assessment method and the method for determining the best treatment time of open-pit mine goaf was proposed, according to such theories as structural mechanics and mechanics of materials, established corresponding relations between the smallest security thickness of goaf and goaf span. This has extremely vital significance for guiding the safe production of open-pit mine.
